Question

我是Spring框架的新手，特别是Spring MVC。

我正在编写一个代码，该代码在表单中包含Name并将其显示在页面上。所以index.jsp是一个表单类，在点击sayHello按钮时，请求应该转发到另一个页面hello.jsp并打印该消息。但是点击按钮就会出现404错误。据我所知，所有的名称和配置都很好，但它不会去打印消息。

的index.jsp

<h2>Form</h2>
<form action="./hello.html">
Name: <input type="text" name="name"/><br>
<input type="submit" value="sayHello"/>
</form>

的web.xml

 <?xml version="1.0" encoding="UTF-8"?>
<web-app version="2.5" xmlns="http://java.sun.com/xml/ns/javaee"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd">
  <display-name>HelloWorld</display-name>
  <servlet>
    <servlet-name>helloworld</servlet-name>
    <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
  </servlet>

  <servlet-mapping>
    <servlet-name>helloworld</servlet-name>
    <url-pattern>*.html</url-pattern>
  </servlet-mapping>

</web-app>

HelloController.java

 package com.spring.mvc.controllers;

import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.RequestMapping;

@Controller
public class HelloController {

    @RequestMapping(value = "/hello.html")
    public String testMVC(Model model) {
        model.addAttribute("message", "Anshul !!");
        return "hello";
    }
}

的HelloWorld-servlet.xml中

    <?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xmlns:context="http://www.springframework.org/schema/context"
    xmlns:mvc="http://www.springframework.org/schema/mvc"
    xmlns:p="http://www.springframework.org/schema/p"
    xsi:schemaLocation="http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-3.2.xsd
        http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd
        http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.2.xsd">

    <mvc:annotation-driven/>

    <context:component-scan base-package="com.spring.mvc.controllers" />

    <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
        <property name="prefix" value="/WEB-INF/views/" />
        <property name="suffix" value=".jsp" />
    </bean>
</beans>

的hello.jsp

  <%@ page language="java" contentType="text/html; charset=ISO-8859-1"
    pageEncoding="ISO-8859-1"%>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-1">
<title>Insert title here</title>
</head>
<body>
<h1>${message}</h1>
</body>
</html>
